Deep unjoy. Is there any reason not to do both of these things - It
wouldn't be that difficult. I remember a saying 'Things should be as
simple as possible, but no simpler'. It seems to me that this SAX effort
might be letting the quest for simplicity eliminate a whole heap of
useful applications.

I agree, but your example implies that my comments were about the data,
rather than about the structure itself - I guess I should have pointed
out that I'm interested in comments in the DTD, so that the DTD can be
documented automatically. This is more like javadoc/idldoc. I'd love an
xmldoc tool. I'm guessing now that SAX doesn't give me DTD events.

I guess SAX is not that useful for me given it's intention (although I'm
pleased to see your effort). Back to the drawing board for me :(
